Autodesk has an LT suite that bundles Inventor 2016 and AutoCAD 2016, the affordably priced versions of the two main programs, in which you can move between 3D-CAD mechanical engineering designs and 2D-CAD drawings and vice versa.

The AutoCAD Inventor LT Suite now makes parametric modelling cost-effective and practical. Importing PDF files, centerpoints, collaborating with colleagues or customers are just a few of the things you can do. Increase your productivity, buy a 2019 licence now, and automatically get the right to use AutoCAD Inventor Suite LT 2016. (further information on licensing).
